CVE-2023-22849
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn improper neutralization of input during web page generation ('Cross-site Scripting') [CWE-79] vulnerability in Sling App CMS version 1.1.4 and prior may allow an authenticated remote attacker to perform a reflected cross-site scripting (XSS) attack in multiple features. Upgrade to Apache Sling App CMS >= 1.1.6
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceApache Sling App CMS versions 1.1.4 and prior contain a reflected cross-site scripting (XSS) vulnerability (CWE-79) in multiple features. An authenticated attacker can inject malicious JavaScript through unsanitized input that gets reflected in web pages, potentially allowing session hijacking or credential theft.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Apache Sling App CMS versionLocate the version information in the application's admin interface, pom.xml, or the bundle/version manifest file typically found in the CMS installation directoryAffected if The installed version is 1.1.4 or any version prior to 1.1.6
-
Confirm the CMS web interface is accessibleAttempt to access the Apache Sling CMS login page or admin dashboard via HTTP/HTTPS to verify the application is running and reachableAffected if The CMS web interface is exposed and accessible to network users
-
Verify authentication is configuredCheck whether the CMS requires authentication for access, or if anonymous/unauthenticated access to admin features is possibleAffected if Authentication is not enforced or anonymous access to privileged areas is permitted
-
Identify exposed input fields in CMS featuresNavigate to common CMS features such as content editing, user management, or configuration pages and identify input fields that accept user-supplied dataAffected if Input fields in CMS features accept unsanitized user input that gets reflected in response pages
-
Check application logs for suspicious input patternsReview CMS server logs for unusual JavaScript tags, script alerts, or XSS probe patterns in request parametersAffected if Logs contain evidence of XSS probe attempts or unexpected script-related content in request parameters
You are affected if your Apache Sling App CMS version is 1.1.4 or earlier, the web interface is accessible, and user input from authenticated sessions can be reflected without sanitization in web pages.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.1.6
Upgrade Apache Sling App CMS to version 1.1.6 or later to address the input sanitization gaps that enable reflected XSS attacks.
Apache Sling App CMS 1.1.6
- 1. Create a complete backup of the current Sling CMS installation including database and configuration files
- 2. Download Apache Sling App CMS version 1.1.6 or later from the official Apache Sling distribution (sling.apache.org)
- 3. Stop the currently running Sling CMS instance
- 4. Replace the existing Sling CMS application files with the new version 1.1.6 files
- 5. Review and update any custom configurations or plugins that may be affected by the upgrade
- 6. Start the Sling CMS service and verify successful initialization
- 7. Test the application functionality to ensure the upgrade did not introduce regressions
- 8. Verify that the XSS vulnerability is remediated by testing the affected features
